Clone Host Grade Applications
Polyclonal Rabbit Affinity Purified E B FC
Stat5 is activated in response to a wide variety of ligands including IL-2, GM-CSF, growth hormone and prolactin. Phosphorylation on residue Tyr694 is obligatory for Stat5 activation (1,2). Stat5 has been found to be constitutively active in some leukemic cell types (3). Phosphorylated Stat5 is found in some endothelial cells treated with IL-3, which suggests its involvement in angiogenesis and cell motility (4). Stat5alpha and-beta are independently regulated and activated in various cell types. For instance, both isoforms are activated in response to IFN-alpha in B cells, but only Stat5alpha is phosphorylated in response to IFN-alpha in HeLa cells (5). Specificity/Sensitivity: Phospho-Stat5 (Tyr694) Antibody detects endogenous levels of Stat5 only when phosphorylated at Tyr694.
